This research study investigates how communication technologies facilitate sexual violence against young people and what challenges this presents for the Victorian criminal justice system. Based on interviews with young people and professionals working with young people, it examines the effects of technology on the lives of young people, the interface between emerging communication technologies and experiences of sexual violence, and the factors that enable or hinder appropriate legal responses. Communication technologies such as online social networking sites and mobile phones are considered, and their use in identifying and grooming potential victims, blackmail and intimation, sexting, harassment, and pornography.
